Everything you need to know about leaving Smith.ai for ZenAgentic.
On Smith.ai, handling 500 calls requires their Pro Tier ($1,400 for 200 calls) plus 300 overage calls at $9.50/call, totaling $4,250/month for basic message taking. ZenAgentic operates on flat monthly retainers ($3,000–$5,000/mo, average $4,000/mo Grow Tier) covering unlimited inbound minutes, zero overage penalties, deep bi-directional CRM dispatch, and ongoing prompt engineering.
ZenAgentic outperforms pooled human call center operators. Human operators juggle hundreds of client accounts and can only read basic scripts. ZenAgentic's voice models are custom-engineered for your business, accessing your live CRM pricing tables, technician availability, appointment calendars, and technical knowledge base to answer complex customer questions accurately in sub-300ms.
The migration is completely turnkey and takes 14 to 21 days. ZenAgentic's engineering team extracts your existing call scripts, designs your conversational decision tree, configures API integrations with your CRM, and executes automated end-to-end sandbox call testing. Once approved, you simply point your carrier call-forwarding rules to your dedicated ZenAgentic telephony endpoint with zero operational downtime.
No. Multilingual capability is natively integrated into our Google Gemini Live foundation. The system switches dynamically between English and Spanish mid-conversation based on the caller's language, with zero additional per-minute or per-call fees.
Our architecture includes deterministic safety firewalls and warm-escalation triggers. If a caller expresses acute frustration or presents an edge case outside the agent's authorized parameters, the system executes an immediate, seamless warm transfer to a designated in-house staff member or emergency mobile line, complete with a live call summary screen.
